Patent number: 7195866Abstract: Methods are disclosed for the production of anti-self antibodies and antibody fragments, being antibodies or fragments of a particular species of mammal which bind self antigens of that species. Methods comprise providing a library of replicable genetic display packages (rgdps), such as filamentous phage, each rgdp displaying at its surface member of a specific binding pair which is an antibody or antibody fragment, and each rgdp containing nucleic acid sequence derived from a species of mammal. The nucleic acid sequence in each rgdp encodes a polypeptide chain which is a component part of the sbp member displayed at the surface of that rgdp. Anti-self antibody fragments are selected by binding with a self antigen from the said species of mammal. The displayed antibody fragments may be scFv, Fd, Fab or any other fragment which has the capability of binding antigen. Nucleic acid libraries used may be derived from a rearranged V-gene sequences of unimmunised mammal.Type: GrantFiled: December 19, 2002Date of Patent: March 27, 2007Assignees: Medical Research Council, Cambridge Antibody Technology LimitedInventors: Andrew David Griffiths, Hendricus Renerus Jacobus Mattheus Hoogenboom, James David Marks, John McCafferty, Gregory Paul Winter, Geoffrey Walter Grigg

Patent number: 6916605Abstract: A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA.Type: GrantFiled: November 20, 1998Date of Patent: July 12, 2005Assignees: Medical Research Council, Cambridge Antibody Technology LimitedInventors: John McCafferty, Anthony Richard Pope, Kevin Stuart Johnson, Hendricus Renerus Jacobus Mattheus Hoogenboom, Andrew David Griffiths, Ronald Henry Jackson, Kaspar Philipp Holliger, James David Marks, Timothy Piers Clackson, David John Chiswell, Gregory Paul Winter, Timothy Peter Bonnert
